DIAL-TRAIN FOR DISTANT-SIGNALING PURPOSES. I

Specification of Letters Patent. Patented D131. 18, 1913- Applicationfiled Ju1y'15, 1910. Serial No. 572,129.

subject of the German Emperor, and resident of Dusseldorf, Germany, haveinvented certain new and useful Improvements in anal-Trains forDistant-Signaling Purposes, of which the following is a specification.

This invention relates to improvements in electric clock signals, andmore particularly to an improved. device for shortly closing one or moreelectric circuits, which is shown on the accompanying drawing, in which-Figure 1 is a. front view thereof, while Figs. 2 and 3 show twomodifications of part of same.

The device is to'serve mainly for electric clock signals and controllingapparatus. Tlhe former are for instance day-clocks,

which are wound up, or by which a gong or bell is actuated, through themedium of an electric current, whereas the controlling apparatus may besuch with a coin insertion.

' Finally, the device can also-be used for advertisement purposes, inwhich for instance electric illuminating bodies are periodically broughtin connection with an electric power source. I

As already mentioned, the closing of an electric circuit is to beeffected in a short way by forming a sliding contact, by which always asafe closing of the circuit is obtained, as the formation of sparks,which act detrimentally on the contact members, is thereby avoided,while, as hereinafter explained, the electric power sourceis usedup in aperfect way. By the sliding contact, the contact members are furtherprevented from sticking to each other in their contact position whichoften occurs with other contacts.

In the example shown in Fig. 1, the axle a disk 5 is mounted, whilethrough the me- "dium of a toothed gearing a star wheel 6 is i set inrotation by the former. Thereby, the disk 5 is periodically brought incontact with a contact spring 7', which is [correspondingly raised bythe wheel 6 and connected with the wire lO and adapted to be regulatedby means of a screw 9. The duration of the, raising of the contactspring 7 which is effected by wheel 6 through the me-' diun of aprojection 8, depends on thewidth of the latter or of the arms of wheel6., Instead. of using two uniformly .moved disks or wheels, according toFig. 2 the disk replaced by a slide 12, which is periodically lifted by'disk 5 and which, owing to its lateral movement being limited, isfinally liberated, whereupon it falls down. and.

When lifting slide 12, it is so keptand moved'by touch with spring The improved contact device may also beadvantageously used in connection with i windin -u arran 'ements forclocks in .which a weight may be connected with an armature. To keepsaid weight always in', equal action, the circuit closing device is atshort periods operated from theclockwork, 96
